We observed the Fermi/LAT GRB 160521B (Veres et al., GCN 19434) with the 
AMI Large Array at 15 GHz on 2016 May 24.75, May 27.65, and Jun 03.73 
(UT) as part of the 4pisky program. We do not detect any source at the 
XRT location (Page et al., GCN 19448), with 3sigma upper limits of 108 
uJy, 108 uJy, and 117 uJy respectively.

We thank the AMI staff for scheduling these observations. The AMI-GRB 
database is a log of all GRB follow up observations with the AMI, and is 
available at http://4pisky.org/ami-grb/.
